ABOUT YOU   We are looking for a Senior iOS Engineer who is architecturally strong, quality-driven, and AI-native to join our Mobile Engineering team. The best candidate will be someone who thrives in a fast-paced, highly collaborative, and exceptionally dynamic setting and is excited to own iOS architecture decisions, ship polished Swift applications, and set the standard for how AI accelerates engineering at Xsolla.

  Deep expertise in modern Swift is essential - SwiftUI, Swift Concurrency (async/await, actors, structured concurrency), and the Apple platform frameworks - along with a proven track record of shipping commercial applications to the App Store from concept to launch. The ability to design scalable architectures, implement robust testing strategies, profile and optimize launch time, scroll performance, memory, and battery, and mentor other engineers while collaborating across cross-functional teams will be key to your success in this role.

  We build AI-first. We expect you to work fluently with AI coding agents as a daily multiplier - scoping work for them, reviewing what they produce with a critical eye, and building the internal tooling, context, and evaluation habits that make the whole team faster.   If you’re passionate about building high-quality iOS experiences that scale, and love shipping apps that power gaming, virtual currency, and digital commerce experiences, we would love to hear from you!

Responsibilities: Design, build, and maintain our native iOS application in Swift and SwiftUI, used by players and developers worldwide.

Deliver high-quality features on time throughout the development lifecycle, from technical design through release and post-launch iteration. Own the full iOS release process: code signing, provisioning, TestFlight distribution, App Store review and submission, phased rollouts, and crash triage. Implement best practices for iOS development, including code review, automated testing strategies, and CI/CD with Xcode Cloud, Fastlane, or equivalent.

Integrate mini-apps, payments, and virtual currency systems into the Xsolla App ecosystem. Collaborate with product and design teams to turn business goals into experiences that feel genuinely native. Work with cross-functional teams, including backend developers, QA engineers, and project managers, and communicate effectively across distributed, multi-timezone teams. Participate in technical discussions to align development work with business objectives.

Architecture & Design: Design and implement scalable application architecture for iOS with a focus on maintainability, performance, and developer experience. Lead architectural decisions around modularization, dependency injection, navigation, and state management (MVVM, TCA, or Observation-based approaches). Configure and optimize the Xcode build graph, Swift Package Manager dependencies, and modular targets for fast, incremental builds.

Build and maintain an internal SwiftUI component library and design system implementation. Establish and enforce coding standards, design patterns, and best practices across the mobile development team. Create technical specif
